Stereographs (also called stereograms) were double photographs intended
to be viewed with a stereoscope to give a three-dimensional impression
of the subject. By 1900, stereographic sets documenting world events or
famous works of art and architecture were so popular that they were sold
in department stores and door-to-door. This set of stereographs was published
by the Collection Stereoptique Felix Potin and records this last and largest
exposition of the 19th century. Other images of the 1900 Paris Exposition
in the Photographic Archives' collection include albums by Neurdein Freres.
